Since Conversations are an integral part of Agile there are some enhancements that would make V1 more useful....
As a team member, I would like to be able to indicate if a conversation is open or closed, so that I know if there are questions that need to be addressed. I'd also like to see the number of open conversations for a backlog item on various pages (e.g. Detail Tracking, Story Board).
I'd also like to make it easier to add the whole team (or many members) to the conversation (bulk add, or list with checkboxes, etc).
